Project Bento Resources and Information

Welcome to Project Bento! As we mentioned in our announcement, Project Bento is adding new bones and attachment points to the avatar skeleton. Bento is now ready for testing!

What is the test period for? How long will it last?

The testing period is designed to validate the viewer and the new skeleton, and will continue until we are confident that we have a solid release candidate, at least a few weeks.

During the course of testing, we may make changes to the project viewer or the skeleton as a result of user feedback. This means test content created during this period may cease to work properly if the skeleton changes.

At the end of the test period, Bento will become a viewer release candidate, and the new skeleton will be enabled on the main grid. Hopefully not long after that, the Bento viewer will be released as the default viewer.

Where can I find the test viewer?

The latest project viewer is always available on the Alternate Viewers wiki page..

The first version is here

Where can we test Bento? How are the test regions special?

Testing Bento will require uploading and using meshes and animations that take advantage of new joints. It will also allow you to take advantage of new attachment points associated with some of the new joints. To do all this, you will need to do your testing in areas of Aditi where such content is specifically enabled for upload, and where the new attachment points are recognized.

Most of Aditi should work, but some regions may not - these are the ones we will be sure to keep up to date, so if you have a problem, please recheck it here first:

• Mesh Sandbox 1
• Mesh Sandbox 2
• Mesh Sandbox 3
• Mesh Sandbox 4

Also, note that the test regions have some new constraints set for mesh and animation upload:

• Animations cannot include animation of positions, except for the pelvis.

  This has always been enforced in bvh upload, but it has been possible to bypass the constraint by uploading animations as .anim files. In the Bento test regions (and on Agni once Bento is fully released), this will no longer be possible.

• Meshes rigged to attachment points cannot be uploaded.
• Animations applied to attachment points cannot be uploaded.

We understand that any new restrictions may be controversial, and do please note that currently these are only being applied on Aditi. The reason we are putting the restrictions in place is to help with testing and transitioning to the new skeleton:

The previous approach was never officially supported and has some significant issues. Moving the attachment points means they are no longer in their intended locations, to support attachments in those areas, as originally designed. Animating positions also has its own set of issues, such as making it easy to get your avatar stuck in a distorted shape.

Adding new joints to the skeleton is intended to alleviate the need for workarounds such as rigging to attachment points, so we need to know whether it is succeeding. Are there things the new system still cannot do? We can only find issues with the new skeleton if it is being exercised as designed.

So please let us know! The most helpful feedback will let us know about problems or limitations encountered with the new skeleton.

How can we test Bento?

There are two ways to help with testing Bento:

• If you are a content creator, please help us exercise the new skeleton. Create your own meshes and animations for facial animation, hand gestures, wings, tails, and so on! Let us know about any problems you encounter, and share your experiences with other creators in the Creation Forum Thread
• If you are a mesh user, help us test the viewer. Try uploading and using some of the test content. Are there any problems displaying or using it on your system? Do you see a significant impact on performance when using the new skeleton?

I found a problem? How can I give feedback?

1. Submit bugs in Jira in the BUG project: please put [Bento] in the summary line.

If you have a display problem, please try with hardware skinning enabled and disabled

Me->Preferences->Graphics->Advanced->Avatar Rendering->Hardware skinning checkbox

Does changing that setting affect the display?
